Answer:
No Change
Step-by-step explanation:
If you add all of the numbers, you get 32. When you divide it by how many numbers there were, you get 4. When you add 4 to 32, you get 36 and since you added one more number, you need to divide 36 by 9, which still makes 4.
In a sale, a shop reduces all its prices by 10%.
On the last day of the sale, the shop reduces the sale prices by 20%
On the last day of the sale, a mobile phone costs £432
How much was the mobile phone before the sale?
Answer:
The phone roughly cost 302 dollars
Step-by-step explanation:
10% of 432=43.2
20% of 432=86.4
432-129.6=302.4

What is the length of DE?
Answer:
D. 6
Step-by-step explanation:
Suppose the triangles are similar:
The side lenghts would be proportional as follows
XZ/DF = XY/DE

Answer:
5,630.81$
A = 5000(1 + (0.04 × 3)) = 5600
A = $5,630.81
what’s the answer to this problem , figure out the area and perimeter of this triangle
Answer:
A: 0.3318 m^2 P: 2.66
Step-by-step explanation:
The perimeter is only adding each of the side lengths, so that's not much of an issue. The equation for the area of a triangle is A = (b x h)/2, with "b" being the base length and "h" representing the triangle's height. We must first multiply the base and height, 0.84 x 0.79. This makes 0.6636 which we will then divide by 2. Our area is now proven to be 0.3318 square meters.
Each bowl can hold 3 tomatoes. There are a total of 16 tomatoes. How
many bowls do you need!
6 bowls can hold 16 tomatoes.
Given:
Total tomatoes: 16
Each bowl holds: 3 tomatoes
Explanation:
To find the number of bowls needed divide total tomatoes by tomatoes each bowl can hold.
Solve:
16 ÷ 3 = 5.333...
So, we need more than 5 bowls, [6 bowls] to hold the tomatoes.
Answer:
6 bowls
Step-by-step explanation:
So . .
If 1 bowl can hold 3 tomatoesThen . .
Simply divide 16 by 316/3 = 5.33You will need 6 bowlsReason. .
Because you must be able to hold all 16! Therefor you round!

Find the equation of the line shown. y 4 3 2 1 Х -2 -3 4
Answer:
y = 1/2x + 0.5
or
y = 1/2x + 1/2
Step-by-step explanation:
y = mx + b
b is y-intercept:
when x = 0, y = 0.5 (when the line cross the vertical (y) axis of the graph)
the point is (0, 0.5) so b = 0.5
m is slope:
slope = rise / run
rise = 1
run = 2
for every 2 x values, y increase by 1
slope (m) = 1/2

What line would be perpendicular to y − 3=4(x+2)?
A. y − 3=−4(x+2)
B. y − 3=1/4(x+2)
C. y − 3=−1/4(x+2)
D. y − 3=4(x+2)
The line perpendicular to y - 3 = 4(x+2) is y-3 = -1/4(x+2)
When are two lines said to be perpendicular?Two lines are said to be perpendicular if the product of their gradient is -1.
which means m1 x m2 = -1
Analysis:
y - 3 = 4(x+2)
y = 4x + 8+3
y = 4x + 11 m1 = 4
so m1 x m2 = -1
m2 = -1/4
so from the options, the equation with a gradient x = -1/4 is C, y-3 = -1/4(x+2)
In conclusion, the line that would be perpendicular to y - 3 = 4(x+2)

write 17/28 and 11/28 as a fraction, percent, ratio and find the difference
please help me with this question
Answer:
17/28
60.7%
17:28
11/28
39.3%
11:28
Difference: [tex]\frac{3}{14}[/tex]
Explanation:
A fraction can be turned into a percent by dividing the numerator by the denominator and multiplying the result by 100%.
For example:
17/28 = 0.607
0.607 * 100% = 60.7%
A fraction can be turned into a ratio by writing it like this:
numerator:denominator
For example:
11/28
11:28
To find the difference between 2 fractions with the same denominator, simply subtract the 2 numerators.
For example:
[tex]\frac{17}{28} - \frac{11}{28}[/tex]
You subtract 11 from 17, then put the resulting 6 in the fraction with the same denominator. This results in [tex]\frac{6}{28}[/tex] which can be simplified to [tex]\frac{3}{14}[/tex].

Sadie earns $10.50 per hour. Do her earnings vary inversely or directly with her number of hours worked? Determine how many hours she worked in a week if her earnings were $210.
Sadie's earnings varys directly with the number of hours worked.
The number of hours worked in a week where her earnings would be $210 is 20 hours.
What is direct variation?
Direct variation is when two variables move in the same direction. If one variable increases, the other variable increases. Sadie's earnings increase with hours worked. This is a direct variation.
How many hours would be worked when earnings is 210?
Hours worked = Total earnings / earning per hour
210 / 10.50 = 20 hours

One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. How many more calories from fat are provided by a 100- calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels?
Answer:
50 calories
Step-by-step explanation:
One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. The fraction that comes from fat:
= 90/150 = 3/5
One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. The fraction that comes from fat here:
= 12/120 = 1/10
The fat that are provided by a 100 calorie serving of the microwave popcorn would be:
= 3/5 × 100
= 60
The fat that are provided by a 100-calorie serving of the pretzels would be:
= 1/10 × 100 = 10
The difference from fat that are provided by a 100 calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels would be:
= 60 - 10
= 50 calories
Hannah and Anthony are siblings who have ages that are consecutive odd integers. The sum of their ages is 92. Witch could be used to find Hannah's age, h if she is the older sibling?
Answer:
The equation to find Hannah's age is 2h - 2 = 92.
This yields Hannah's age as 47 years.
Step-by-step explanation:
Let h = Hannah's age.
Hannah is older than her sibling, and their ages are consecutive odd integers. Therefore, h = an odd number and the sibling's age = h-2.
The sum of their ages is 92, therefore
h + (h-2) = 92
2h - 2 = 92
2h = 94
h = 47 years

Quadrilateral Identified:
Area: The evidence:
The quadrilateral is a trapezoid and the area of the quadrilateral is 85.04 square units
How to determine the quadrilateral?The vertices are given as:
A:(-2, 3) B:(4, -6) C:(10, 2) D:(6, 8)
Next, we plot the vertices (see attachment)
From the attached graph, we can see that the quadrilateral is a trapezoid
How to determine the area?From the plot, we have the following features:
Height: AD
Parallel sides: CD and AB
Calculate the lengths using:
[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]
So, we have:
[tex]AD = \sqrt{(-2 -6)^2 + (3 -8)^2}[/tex]
[tex]AD = \sqrt{89}[/tex]
[tex]CD = \sqrt{(10 -6)^2 + (2 -8)^2}[/tex]
[tex]CD = \sqrt{52}[/tex]
[tex]AB = \sqrt{(-2 -4)^2 + (3 +6)^2}[/tex]
[tex]AB = \sqrt{117}[/tex]
The area is then calculated as:
Area = 0.5 * (CD + AB) * AD
This gives
Area = 0.5 * (√52 + √117) * √89
Evaluate
Area = 85.04
Hence, the area of the quadrilateral is 85.04 square units
